METALLIC RECEPTACLR Application filed Ang-ust 27, 1919. Serial No. 320,268.

vOhio, has invented certain new and useful Improvements inl Metallic Receptacles, of which the following is a specification.

This invention relates generally to metallic receptacles, and has particular reference to an improved metallic can wherein is embodied improved features of construction for strengthening the can structure as a whole and in this manner to promote and lengthen its period of usefulness.

Another object of the invention resides in a sheet metal receptacle wherein is employed a tubular body having one end closed by means of a suitable bottom and the opposite end open in order that various commodities may be positioned within the can or receptacle, and the openend thereof being provided with an overlapping portion which extends downwardly and in parallel relation with the wall of the receptacle for a suitable distance so that said wall around the open end will be substantially doubled and in this manner prevented from bending or twisting in a distorting manner, the lower extremity of the overlapping portion being provided with a bead in which a reinforcing member is positioned, said member being disposed to extend around the body of the receptacle so that the general rigidity` of the latter will be considerably enhanced.

Other objects of the invention reside in a metallic can structure which may be formed from relatively inexpensive thin sheet metal and yet by being reinforced in accordance with the principles of the present invention, said structure will possess the durability and general rigidity of a similar structure formed from much heavier material, to provide simple and effective means for uniting the adjoining vertical meeting edges of the can and in the provision of a reinforcing band between the overlapping portions of the open upper end and the wall of the receptacle which further assists in strengthening this portion of the receptacle, and 1n means of a bead 4formed upon the lower end of the receptacle, said bead serving as a. base for the receptacle as a whole.

For a further. understanding of the invention, reference is to be had to the followmg description and to the accompanying drawings. in which:

Similar characters of reference denote like and corresponding parts throughout the several views of the drawing.

Referring more particularl to the form of the invention disclosed in igures 1 to 5, inclusive, use is made of a metallic can or receptacle 1', which may be employed for any number of varying purposes and may contain any suitable materials. In the embodiment of the invention under discussion, the receptacle is formed from a blank of sheet material of relatively thin gage, and this blank is bent preferably to assume a substantially tubular contour. By thus forming the receptacle, the vertical edges of the blank of material unite in a joint, as is indicated by the numeral 2 and this joint is sealed by means of a vertical strip 3, which may extend substantially the full length or height of the receptacle. Through the medium of a spot welding process, or its equivalent, the strip 3 may be securely united -ing elements, such as rivets.

may be maintained and rigidity in connection established. This manner of securing a joint- 2 also possesses a considerable, commercial advantage in that it is.very economical to produce.

Inserted in one end of the receptacle is a bottom 4, which is of substantially dish shaped cross sectional formation and by 'bein'g thus formed compensates for inequalities caused by the expansion and contraction of the metallic materials and also serves enables the latter to withstand the usually severe jolting and jarring consequent to general service. The bottom member is secured in placewithin the receptacle by spot welding the flange 5 to the adjacent wall of the receptacle or by the use of suitable fasten- The extreme lower end of said receptacle is bent to provide a substantially circular scroll shaped bead 6, which is of relatively enlarged contour and 'provides a substantial restlng base for the receptacle 1 and serves in a great measure to prevent undue tilting of the latter. The bead terminates in engagement with the wall 5 so as to seal the lower end of the latterv and atthe same time to serve in l preventing undue 'separation of said flange from its established relationship with the inner wall of the receptacle.

In order to reinforce the open upper end portion 7 of the receptacle and to overcome a weakness found in many of the receptacles of the particularform to which this invention relates, the wall of said receptacle terminates in an overlapped and downwardly extending portion 8, which is disposed to lie parallel and in spaced relation with respect to the adjoining portions 7 of the receptacle and the portion 8, intermediate of its length, is preferably provided with a reinforcing bend 9 which materially contributes to the rigidity of the upper end of the receptacle. The portion 8 1terminates in an upwardly directed wall 10, which is disposed to lie between vthe portionsv7 and 8 and said wall 10 terminates contiguous to the upper end of the receptacle. Through the provision of the walls 7, Sand 10 a structure is provided around the open upper end of the receptacle of considerable thickness and consequently marked strength and rigidity is imparted to this usually weak portion of the receptacle, in this manner the latter is enabled to withstand the knocks andwear of hard usage and will nbt be' likely to lose its original shape or form. It will be observed that the portion 8 andthe Wall 10 lie in physicalcom' tact with the wall of the receptacle', so that when the latter is dipped with a suitable galvanizing material thel latter will not be'likely to drip or collect 'objectionably laround points contiguous toet-lie lowerterminating end ot' the reinforcing structure. In? the manufacture of the receptacle, the, parts forming the reinforcing structure are bent to assume their proper positions before the rereptacle is shaped to resume its tubular formation, and consequently a vertical joint 11 is formed in said reinforcing structure vin alignment with the joint 2. To strengthen this joint 11, use is made of a bridge plate 12 which is positioned so as to be located b6- tWeen the outer overlapped portion 8 and the wall 7 of the receptacle. This plate bridges the joint 11 and by means of a spot welding or riveting process the same may be securely retained in place.'y If desired, the wall 10 couldl be recessed to receive the plate l2 so thatbulgin in the reinforcin structure will be elimlnated but, obvious y, said plate may be inserted between the walls 8 and 1() if found expedient. rlhe lower edge of the plate 12 may be crimped as is indicated by the numeral- 13, and this crimped ortion is adapted to be received within the end 9 of the wall 8.

The principles `involved in the reinforcing structure above described may be carried out in many other different physical embodiments. F or instance,'as shown in Figure 6 the bend 9 may be equipped with a reinforcing wire 14,which is arranged to encircle the upper end of the receptacle. Through the provision of this wire, it willbe manifest that the general strength of the reinforcing structure will be enhanced. Also, as shown in Figure 7 the overlapping wall8 terminates immediately adjacent to the inner wall 7 of the receptacle, and in this form the wall 10 is omitted. In certain light structures, the use of the Wall 8a in combination with the reinforcing Wire 14 is sufficient to impart all required rigidity to a receptacle wherein the.

same is not obliged towithstand severe distorting stresses. Again, as shown in Figure 8, the wall 1()a may be formed separately from the overlapping portion 8. This structure may be econoncally produced in thatthe' wall 1()a may be formed from scrap mawill be provided which will be'capable of impartin relatively extended service. Moreover, t rough the reinforcement described a receptacle may be formed from relatively thm sheet metal and yet will possess a maximum degree of general strength and rigidity. In the modification disclosed in Figure 9, the vertical joint 2 is produced by simply overlapping the meeting edges of the Wall of said receptacle, which overlapped edges may be secured in any suitable manner. This construction eliminates the use of the strip 3.

, In the preferred forms of the invention, it

Will be observed that the reinforcing structure as a whole terminates in contact with and immediately adjacent to the outer wall of the receptacle, and by positioning the parts in this manner streaks or other objectionable disfigurations will be eliminated from the receptacle after the latter is galvanized.

What I claim is:

In a receptacle of the class described, the combination with a sheet metal body comprising a closed lower end and a normally open upper end, of means for reinforcing l0 ARTHUR MILLER.
